Robot Housing Contact Detection for Active Motion Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not sufficiently utilize unexpected motions of robots, such as those generated by physical interactions, for entertainment purposes.
Innovation Solution
An information processing device with a measured value acquisition section, contact event detection section, and activeness determination section to detect and determine the activeness of contact events on a robot's housing, using measured torque and angle difference values to identify moved portions and predict active contact events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contact events are detected on all parts of the housing, then detection coverage is improved, but false detection from non-active contacts increases
Solution Approach 1:
The patent applies local quality by differentiating detection sensitivity across different parts of the housing. Moved portions (attaches/detaches) are monitored with higher sensitivity while non-moved portions are monitored with lower sensitivity or not at all. This allows accurate detection of active contacts on moved portions without false detections from incidental contacts on non-moved portions.
Solution Approach 2:
The patent implements dynamics by dynamically adjusting which parts of the housing are monitored for contact events based on real-time motion state information. The detection system adapts to the current operational state, focusing monitoring resources on moved portions where active contacts are most likely to occur, rather than statically monitoring all housing parts equally.
2Ease of operation
If the robot responds to all detected contact events, then interaction responsiveness is improved, but inappropriate responses increase
Solution Approach 1:
The patent uses feedback by continuously monitoring the motion state of housing parts and using this information to evaluate detected contact events. The system feedback loop determines whether a contact event occurred on a moved portion, and this evaluation feedback controls whether the robot generates a response, ensuring responsive yet appropriate interactions.
3Measurement precision
If motion sensors are installed on all housing parts, then detection coverage is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by making the motion sensors multi-functional. The same sensors that detect the robot's overall motion state are also used to determine whether specific housing parts are moved, eliminating the need for separate sensors on each housing part and reducing system complexity while maintaining detection coverage.

AI summary
Provided is an information processing device including a measured value acquisition section, a contact event detection section, and an activeness determination section. The measured value acquisition section acquires a measured value indicative of a change in the motion state of a part of a housing. The contact event detection section detects, on the basis of the measured value, a contact event that has occurred on the part of the housing. The activeness determination section determines, in a case where the contact event is detected on a moved portion included in the part of the housing, that the contact event is active.
